Speaking of The Witcher (story above), The Witcher Website now offers a new patch for The Witcher 2: Assassins of Kings Enhanced Edition to update CD Projekt RED's RPG sequel to version 3.2. The patch is mirrored on AtomicGamer and The Patches Scrolls, and the following blurb explain how some of the included changes began as a user-created modification before they hired the mod author:

You can now download the new patch for the PC version of the Enhanced Edition of The Witcher 2: Assassins of Kings. It upgrades the game to version 3.2 and modifies the UI significantly. This update is enabled by default but is optional and can disabled in Configurator DLC Menu. If you encounter problems with the automatic patching system, please download the patch manually from here (For full list of changes, also click here).

Now, if you’re thinking to yourself “These changes sound familiar”, you are right! David Block, who originally created the modification described above, now works at CD Projekt RED and is the author of this patch. Thanks to your feedback, he was able to improve some of the elements and make it even better than before.

I love it when companies hire people who make awesome mods. They've proven that they know how to make a game even better than it was when it came out, so there's not much reason to think they can't just keep on doing that, only this time before it comes out.
